Recorders, players and tape machines cover a huge range of devices designed for recording and reproducing audio in all available media formats. From reel-to-reel tape machines from the beginning of the 20th century to portable digital field recorders now used in TV and movies. There are the ones that can only reproduce one media format such as gramophones and turntables, those which can be multi-task by recording and playing back such as cassette, VHS, LaserDisc (LD), MiniDisc (MD), analogue ADAT, and so on until we reach modern day digital hardware and all its formats; AIFF, OGG, WAV, MP3, FLAC, etc.
